COMBlNED DROPPER AND LIQUID-MEASURER, RECORDING-DIAL, ANDDOSE-INDICATOR.

SPECIFICATION forming part of Letters Application filed June 26, 1899.

T0 to whom, it may concern:

Be it known that I, FERNAND SALOMON, of

Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and Improved Combined Dropper and Liquid-Measurer, Recording-Dial, and Dose-Indicator, of which the following is a specification. My invention relates to an improved construction of automatic dropper and measure adapted for use in connection with bottles or vessels containing medicinal solutions or other liquids, the same being designed to receive therein a portion of the contents of the bottle in predetermined quantities and from which the said medicinal or other liquid solutions may be wholly discharged or expelled drop by drop at the will of the user.

One object of 'my invention is to provide in a simple and inexpensive manner a device of this character which will not only discharge the contents drop by drop, but measure each dose of the contents or a fraction thereof in an accurate manner, thus insuring the same quantity at each operation.

A further object of my invention is to provide in connection therewith a recording-dial to be used by the invalid or attendant to indicate the time at which the. medicine is to be administered-and the number of drops to be taken if the medicines are to be used in that way.

A still further object of my invention is'to provide an improved construction of cork which is adapted to fit the neck of bottles of varying sizes ranging from those of a very small diameter to those of a comparatively large diameter.

My invention consists of a reservoir which in size may be capable of holding a tablespoonful or more, if desired, said reservoir having a flexible diaphragm or closure, a cap adjacent said diaphragm having an air-inlet leading into said reservoir and'a closure therefor, and a dial for indicating the hour or fraction thereof at which the next dose is to be administered and for indicating the number of drops to be used if the medicines are to be taken in that way.

My invention further consists of the novel features of construction and arrangement of Patent at. 650,617, dated May 29, 1900. Serial a. 721,974. (No model.)

parts, all of which will be hereinafter fully described, and particularly pointed out in the appended claims.

Figure 1 represents a side elevation of the neck of a bottle, showing my invention applied thereto. Fig. 2 represents a central vertical section thereof and Fig. 3 represents a plan view.

Similar reference-numerals indicate corresponding parts in all the figures of the drawings.

Referring to said drawings, 1 designates the neck of an ordinary bottle, and 2 designates my improved combined automatic liquid dropper and measurer, time-dial, and doseindicator, the same consisting of a reservoir 3, having a contracted neck or extension 4, which is shown of a lesser diameter than the diameter of the neck of the bottle.

5 designates a cork having a central bore which is adapted to the reduced neck or extension 4, the external surface of said cork being formed with a plurality of annular steps 6', each step from the uppermost to the lowermost being of reduced diameter, so that the same may be fitted to the necks of bottles whose diameters may vary.

The upper end of the reservoir 3 is provided with a flexible cap or diaphragm 7, having an annular recess 7, in which the upper edge of the reservoir fits, thus forming a closure for the same, said diaphragm being provided with a central opening 8 for the reception of a flange 9, which depends from and forms a part of a disk or plate 10. The ex terior of said flange is provided with an annular bead 11, which when the same has been forced into the opening 8 of the diaphragm 7 and the walls of said opening have closed in around said annular bead 11 serves to re tain said disk or plate securely in place, as clearly shown in Fig. 2.

The lower end of the opening 8 serves as a seat for a valvel2, the latter being secured to a stem 13, which projects up through the opening 13 in the flange 9, the upper protruding end of said stem being provided with a finger 14, arranged adjacent to and adapted to register with a dial 15, formed on the upper face of the disk or plate 10.

As will be observed, the figures of the disk said disk 10, the same being free to be movedso as to indicate the number of drops to be administered if the medicine is to be taken in that way. 1

18 designates a coil-spring which is disposed betweenthe under side of the finger 14 and the upper face of the disk or plate 10, by means of which the valve-stem is normally pressed upwardly, so that the valve is held firmly against its seat, and whereby also the finger 1a is frictionally held against accidental rotative movement.

The operation of myinvention is as follows: When the specific gravity of the contents of the bottle is comparatively low, the same will freely flow into the reservoir 3 through the neck 5 by inverting the bottle, said liquid being afterward held in the reservoir by atmospheric pressure. lhe reservoir after having been filled in this manner is removed from the neck of the bottle, and when it is desired that the contents or any portion thereof shall be discharged in drops the disk or plate 10 is pressed upon by the fingers, so as to compress the flexible diaphragm, whereupon a single drop will be expelled. A releasing of the pressure upon the disk or plate 10 will cause the diaphragm to assume its normal position ready for another depression. In this operation it will of course be understood that the valve 12 will remain on its seat, so as not to equalize the atmospheric pressure.

When it is desired that the whole contents shall be emptied, a pressure of the finger upon the protruding extremity of the valvestem 13 will unseat the valve and allow the air to enter into the reservoir, thus equalizing 1. A device of the character described, comprising a reservoir adapted to the neck of a bottle, said reservoir having a flexible diaphragm or closure, a cap adjacent said diaphragm and having an air-inlet leading into said reservoir, a closure for said air-inlet, and a dial forindicating the hour or fraction thereof at which the medicine is to be administered, and for indicating the number of drops to be used.

2. Adevice of the character described, comprising a reservoir adapted to the neck of a bottle, said reservoir having a flexible diaphragm or closure, a cap adjacent said diaphragm having an air-inlet leading into said reservoir a valve adapted to keep said airinlet normally closed, and a dial for indicating the hour or fraction thereof at which the next dose is to be administered, and for in dicating the number of drops to be used.

3. A device of the character described, comprising a reservoir, adapted to the neck of a bottle, a flexible diaphragm forming a closure for said reservoir, said diaphragm having a central opening, a cap having numerals thereon to designate the hour or fraction thereof at which the medicine is to be administered, and for indicating the number of drops to be taken, said cap having a flange adapted to the opening of said flexible diaphragm, and

forming an air-inlet into said reservoir, a

for said reservoir, a cap adjacent said dia* phragm, said diaphragm having an air-inlet leading into said reservoir, a valve adapted to keep said air-inlet normally closed, and a dial for indicating the hour or fraction there of at which the medicine is to be administered, and for indicating the number of drops to be taken. 5. A device of the character described comprising a reservoir for containing liquid andadapted to the neck of a bottle, a flexible diaphragm or closure for said reservoir having an air-inlet therein, and means for keeping said air-inlet normally closed and for open ing said air-inlet when desired.

FERNAND SALOMON.
